Mine track and switch construction



Aug. 16, 1932. GOFF MINE TRACK AND SWITCH CONSTRUCTION Filed March 4, 1952 Mont gaff 'ATTORNEY Patented Aug. 1 6, '1932 UNITED STATES PATENT-OFFICE MONT earn, or. s'ronn, KENTUCKY 'MINE TRACK AND SWITCH CONSTRUCTION Application filed March @1932. Serial in. season. 7 'j c The invention relates to a mine track and switch construction.

The primary object of the invention is the provision of a Construction of this character,

wherein the switch points are arranged therein in a manner that the same will be sturdy and will be prevented from opening accidentally during the passage of a car upon the main track and also any spreading of such 10 points is eliminated.

Another object of the invention is the provision of a construction of this character, wherein a novel form of tie isrelated thereto and is attached to the rails of the track in a novel manner so that the said tie can be readily removed without requiring the removal of the fastening mediums and also per- Inits the locating of throw mechanism for the switch points at either side of such tie.

A further object of the invention is the provision of a construction of this character which is simple in its makeup, thoroughly reliable and efficient in its purposes, strong, durable, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in I detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawing Figure 1 is a fragmentary plan view of the track and switch construction in accordance with the invention showing by full lines the threw for the switch points at one side of the main track and by dotted lines at the opposite side thereof.

Figure-2 is a sectional view on the line 22 of Figure 1.

Figure 3 is a perspective view of the special form of tie to be located at the switch. 7

Figure 4 is afragmentary plan view showing on an enlarged scale the manner of fastening the rails of the track to the tie.

Similar reference characters indicate corresponding parts throughout. the several views in the drawing.

Referring to the drawing in detaihA designates the rails of the main track and B the rails of the branch or siding track, these rails being of standard construction andare supported upon ties C of any approved type. v

At the point of communication of the main track with the siding or branch are shiftable switch points 5 of a switch and located at this area is a series of ties 6, 7 and 8 respectively. n,

'The ties 6 and 7' are preferably of the metal kind and carry fish plates 9 for the clamping of the rails thereto, the plates being secured through the medium of bolts 10 to said ties.

The tie 8 is located at the opening side. of r the switch and made from metal, of inverted V U-shaped form in cross section having a strengthening rib 11 at the longitudinal center of its channel serving additionally to prevent lateral creeping when the tie 8 is a supported upon a foundation or bed for the track. It of course is understood that in the placing of the tie its channeled side opens downwardly while upon theupper face of said tie are the spaced blocks 12. having the reversely beveled portions 13 upon which play the points 5, the'blocks 12 being integral with the tie 8 and lying between said points 5 so that when the latter are thrown to shut 01f the siding or branch from the main track there will be no chance of accidental opening of the switch to said siding or branch and also such blocks keep the points of the switch from breaking.

Formed in the tie 8 near opposite ends thereof are substantially L-shaped slots 14in which are engaged bolts 15, these carrying rail clamps 16 which engage with the rails of the main track at the outer side thereof and such bolts on the loosening thereof can be shifted in the slots ll to permit the movement of the clamps 16 from engaging the rails without necessitating the removal of the bolts 15 and the clamps from the tie. The

tie 8 has formed therein bolt holes 17 next i to the inner sides of the rails ofthe main track to accommodate bolts 18 carrying rail clamps 19, these being engaged with the said rails at their inner sides and inthis manner the rails are made fast to the tie 8.

Adapted for positioning ateither side of V the main track is a support 20, the same being detachably secured to the tie 8 bya fastener 21 and this support carries a lever 22 for operating a throw 23 for the switch points 5, the throw 23 being connected with the lever at its crank 24: through the medium of a link 25.) On operating the lever .22 the switch can be opened or closed as the throw shifts the points 5 of such switch, the points being m ade fast to the throw 28 through the medium of clamps 26. i V r What is claimed is In a construction of the character described, the combination with main. and branch rail tracks and ties supporting the same, of switch points movably supported for controlling communication between the main and branch rail tracks, :a series of ties beneath said points blocks formed on one of the ties and disposed between the points and having reversely beveled portions for play of said points thereon, .shiftable clamps lcarriedby one of the ties for the main track to engage the outer sides of rails thereof, removable clamps on the last referred to tie andengaging the inner sides ofthe rails, a support attachable to'either end of one tie adjacent to the switch points, a throw lever carried by said support, a throw connected with the switch points, and a connection be tween the throw. and said lever;
